Hi Ian,

Have you considered running the subs as a stereo pair (in a 5.2 setup), with them connected to the G68's AB output?
If you add your equipment in to it including both subs you'll see how to connect and configure them.
Do you use Mconfig? If not you should consider using it, as:

1) It gives you a backup history your config (good if you need to revert for some reason)
2) Lets you visualise Bass Management options
3) Lets you perform Meridian Room Correction (MRC)

Regards,
Carl
